According to a large British study, people with BMI (body mass index) between 35-40 years are almost nine times more likely to develop type 2 diabetes.
Research involving 2.8 million adults suggests that even participants in the study classified as slightly overweight doubled the risk of type 2 diabetes.
People in the BMI class 40-45 are 12 times more likely to develop type 2 diabetes, the results also revealed.
The public health of England called for "permanent actions" on the back of the findings, which was presented to the European Congress on Obesity, which takes place in Glasgow.
While these findings undoubtedly concern, it should be noted that overweight people who are at risk of type 2 diabetes may reduce this risk. People with prediabet have been able to lose weight and improve blood glucose levels by joining our award-winning Low Carb program, which shows how to eat a healthy diet in real eating can lead to health benefits, including prevention of type 2 diabetes.
The results of the BMI study came after scientists followed medical records, including BMI data, contained in the UK Clinical Practice Research Datalink database from January 2000 to July 2018.
They then used hospital information to calculate the risk of developing chronic health conditions. The results were worse for people with health problems (such as high blood pressure) at the start of research.
The results showed that people with BMI 30-35 had a 70% higher risk of heart failure compared to people in the 18-25 BMI brackets. Those with BMI 40-45 had a triple risk of heart failure and high blood pressure as well as abnormal cholesterol levels. People in this 40-45 holder were twice as likely to have premature death for any cause.
Leading author Christiane Haase, who works for investors in the Novo Nordisk study, said: "With the number of people living with obesity, it has almost tripled worldwide over the past thirty years. [105 million people in 1975 to 650 million in 2016]our findings have serious consequences for public health.
British Heart Foundation nutritionist Victoria Taylor added: "More than a quarter of adults in the UK are obese and something we urgently need to do."
The researchers highlighted the fact that the study was observational and irreversible when they said people were included in the study because they were supposed to see their general practitioner to measure their waist for some reason.
